The Ultra 4 remains the large Apple Watch for long days and sports activities. The new generation improves sensor technology and battery life in particular. We show what the data means and what compromises come with the outdoor package.

The Ultra 4 at a glance
Apple introduced the Ultra 4 in September 2026. According to the manufacturer, the German starting price is 899 euros including VAT. The selection is clearly aimed at the large case size. Before you decide on the feature list, it is therefore worth taking a look at the actual size on the wrist.

Battery figures need a clear mode
The largest number on a data sheet does not automatically describe the most detailed recording. Extended workout modes can reduce the frequency or scope of measurements. Therefore, for your tour, the question is which data you need on the go. Navigation assistance, display usage, and cellular connectivity can additionally change consumption.
[2]Plan a longer activity with a reserve, instead of fully pushing the manufacturer's limit. Try out the desired mode before an important tour in a familiar environment. This way you can see if the display and recording details are sufficient for you. A watch whose power management you know is more useful in everyday life than a number you only know from the product description.
What the first independent tests report
CHIP praises the display, features, and extensive workout options in its own test. The editorial team cites the size on thin wrists and partially inaccurate GPS results as criticisms. This is a helpful reminder that a high-quality tracking system does not draw a perfect line on the map under all conditions.
[3]COMPUTER BILD describes the longer battery life as a strength and evaluates the step compared to an Ultra 2 or Ultra 3 as manageable for many users. Especially for Germany, the editorial team points to limitations with new AI features. These experiences come from the tests of the mentioned editorial teams. bandkult did not wear the Ultra 4 itself for this article in a continuous outdoor test.
[4]Using outdoor features effectively
Compass, maps, Action button, and a clearly readable display only help reliably if you set them up before use. Check which maps are available and, if necessary, stored offline. Set the Action button so that it suits your most frequent use, and practice operating it with your usual clothing.
Satellite and emergency call features have requirements and regional limits. A long feature list therefore does not mean that you can use every service everywhere. Find out about current availability before a trip. For demanding tours, a plan suitable for the situation and your own reserve should also be part of your concept.
Size and band determine comfort
The Ultra case is considerably more present than a smaller Series or SE. If you also want to wear the watch at night, test the combination with your preferred band as much as possible. A band can change the fit and weight distribution without reducing the dimensions of the case.
For sports activities, a secure, proper attachment is important. For the office and everyday life, a different material can be more comfortable. Choose accessories expressly according to approval for your Ultra and according to the area of use. Not every fashionable band is rated for water, intensive sports, or high loads. A single universal recommendation would not do justice to the different situations.
Upgrade from Ultra 2 or Ultra 3?
If you reliably get through your workouts and travel days with your previous Ultra, an immediate switch is harder to justify. A valid reason can be a specific new measurement function, a significantly changed scope of use, or an insufficient battery. Write down which limit of your previous model you actually reach.
When comparing used devices, the condition is more important than the generation alone. Check the display, case, buttons, and battery condition, as well as traceable purchase documents. A lower purchase price is attractive, but should fit the possible follow-up costs. For some, a younger used Ultra is a good choice; others deliberately prefer a new device with a clear starting point.
For whom a Series might be the better choice
For regular workouts and normal everyday life, not everyone needs the largest case. If you charge it comfortably every day and prefer a light wearing experience, a Series can be more comfortable. The Ultra plays out its advantages more strongly if you regularly use battery reserve, outdoor operation, and a robust overall package.
Before ordering, you should also check the paired iPhone. According to Apple, the Ultra 4 requires an iPhone 11 or newer with iOS 27. Additional conditions apply to individual smart features. Decide based on the features that are confirmed for your region and your existing devices.
